## Summary
Speed of PCI connections is important. Speed of 8x seems like minimum for rendering and machine learning. PCI lanes need to offered by motherboard and also CPU. 

The pci slots may not operate full bandwith even in case they offer the right hardware slot. Also motheboard dependend. Asus seems to be greatly specific with their motherboards.

### ==> machinelearning
- per card
	- 8x PCIe lanes
	- at least 2 cores 

## Schema of machines?
#### MachineFarm
3-4* 1080 heavy duty media machine

#### FeedFarm
2-3 1080 render, mining machine
